Austrian prosecutors said Friday they are investigating the far-right Freedom Party for alleged incitement of racial hatred after complaints about campaign posters for local elections next month.

The FPOe party’s posters for the election in the western city of Innsbruck carry the slogan “Heimat-Liebe statt Marokkaner-Diebe,” meaning “Patriotism not thieving Moroccans.”

The Moroccan embassy in Vienna issued an angry statement attacking what it called the FPOe’s “defamatory and discriminatory behavior” and accusing it of “humiliating, stigmatizing and discriminating against” the Moroccan community.
